"They wanted to get married, and a mutual friend introduced all of us, and they said, 'Let's get married, can we get married at your house?' and that's how we met and soon after that we became very good friends," Nassif said.

Nassif drove Sheen home from the hospital, but he declined to provide details of their conversation.

"There were things he said I don't feel comfortable" disclosing, Nassif said.

At another point in the interview, Nassif added: "Obviously we all want Charlie to keep his sobriety. No one can push him into it."
